LUBRICATING APPARATUS FOR ENGINES SPECIFICATION formng'part of Letters Patent No. 636,014, dated October 31, 1899.

Original application led September 13, 1894, Serial No. 522,898. Divided and application filed July 1, 1898, Serial No. 684,978. Again' divided'and this-application tiled December 29, 1898. Serial No. 700,615. (No modali) To all whom ,zt .1n/ry concern:

Be it known that I,- BENJAMIN QVANDUZEN,

a citizen of the United States, and a vresident 'of the town'of `\Vinton Placein the county of Hamilton an'dState of Ohio,have invented'certain new-anduseful Improvements in LubricatingA'pparatus for Engines, 'ofwhichthe following is a speclicationf The invention herein set forth is a division' of one forwhichapplication was vfiled July l, 1898, and borethe Serial No. 584,978, andthe said application, Serial No. 6S4,978, is a.' division of an application, semina 522,898,1n1ea dated August-1G, 1898, Due reference is here-l My apparatus although especially designed for engines' driven by carbureted air or gas'- is applicableto other engines.

The several features of my inventionand the various advantages resulting; fromthe'ir use conjoinlly oroiherwise will be apparent from thefollowing description and claims.

Inthe accompanying drawings, making a partof this application, siinilar'letters of reference indicate'corresponding parts.

Inasmuch as my .invention is primarily applicable to engines driven by the explosion of carbureted air or gas, I have for the purposes of sufficient illustration shown my invention as applicable to 'a common kind of. suchl engines.

As my apparatus is 'confined to the pitman and its connections at one end with the cross-v head, I have deemed it sucient to show a cylinder,piston,cross-head, crank, and crankshaft duly assembled and my apparatus duly applied thereto.

Of the drawings, Figure l shows a Vertical section ofthe cylinder, the piston, the crosshead, the journalfbox of the crank-wrist, and the journal-'box of the crank-shaft, while the crank audits wrist andv `certain bolts, dac., as well as portions of the oiling apparatus, are shown in elevation'.- Fig'. 2 represents an enlarged vertical central section of the plunger, receiving-tube,ball-valve, and stop, the latter being show-n in elevation. Fig. 3 repre# foundation.

-to the foundation, preferably by being cast between the jacket and the cylinder..

Q4 is the head of the cylindeiggand Q the space formed therein. The spaces or chambersQ4 and Q5 are commonfto receive water. The latter ischauged as fast as desired, and the cylinder is thereby kept "0001.

The cylinder Q is suitablysupported. A

l preferred means consists of'a foundation Q,

supported upouthe reaches A32. The foundation is preferably cast in one with the cylinder. The crank- Shaft is'also suitably supported. In th'e`present instance the foundation Q9 forms the'snpport for the crank-shaft.

' Throughthecenter. of this foundation isa lhorizontal opening or journal-bearing Q7, in

which latter is present the crank-shaft turning therein;` Between the reaches A2 the foundationjis extended downward ina rectangular extension Q8, substantially as shown, for the purposes of increasing the strength of'lho The cylinder is suitably united 4in one therewith. Through the center of this foundation is a horizontal opening or journalbearing Q7,I in which latter is present the crank-shaft F, turning therein. The crank Qis connected to the crank-shaft F substanti'ally as shown andvin the same manner as is the casein center-crank-shaft engines.

The crank Q9 is provided with a wrist-pin Q10, in turn connected by a suitable box-journal Q12 to the lower end of` a pitman or connectingA rod Q35 Whose upper end is connected, by means ofthe journal-box Q, to the cross-head or wrist Q15, the latter being bolted, by means of studlbolts Q1, to the piston-head Q, the latter being provided with packing, preferably of a metallic kind well known in the arts.

Where the cylinder belongs to an engine of the kind which has a piston'rod, the cross-head will be duly secured to that end of the pistonrod which is opposite where the piston is atvil'i 2 i esame,

5 Q21, hollow within, has a central orifice Q23,

which orifice is enlarged above, forming the passage Q24.- A. ball-valve Q25 rests on. the upper end'of the'narrow passage Q2B and is ail-owed vertical play betweenthe shoulders 'Q25 of the passage Q24 and a stop Q27, located across the passage Q24. )Thepassage Q24 is continued ufp throughthe recess Q82 in the cross-head Q15 and passes to the upper surface l of the' cross-head and within the box Q14'. "The,

operation of this part of the device is as fol- As'the piston descends the lower end of the dipper ent-ers the dip-tube Q29, filled with oil.' The oil is forced up through the passage Q23 of the dipper and leaving the valveQ25 passes around same and into the passage Qzf As thepiston rises the valve QW desceudsand f prevents the oil in passage Q24 from returning through passage Q23.' Successive reciprocain passage Q24 until it (the oil)'soon reaches' the upper side of the box Q1* and lubricates the wrist Q15 of the pitr'nan or connecting-rod. Successive reciprocations of theV piston-head continue to steadily supply the required quantity of oil to the Wrist Qi and journal-bearings Q14of the pitman orconnectingrod. The sight-feed or oilereservor Q18 has an adjustable screwl in common use, whereby the quantity of oildelivered through the delivery-tube vQ19 can be regulated so as to feed the requisite amount of oil, and'no more, Vto the diptube Q20. Attention is called to the fact that the lower portionof the orifice Q23 is conicaliy" enlarged down'n'ardly, substantially as shown vin Fig. 2. 'lfhi's shape is a valuable feature tions oi' the piston increase the amount of oil.

of invention, inasmuch as it enables-the dipper to pump up the oil, Whereas it would not to any extent take it up otherwise, even though the ball-valve Q25 be present. this orifice Q23, tapered, as shown, is present, the dip-tube Q20 can be relied upon to promptly, readily, and alwaystake up the amount of oil that is fed to it by the sightfeed Q18. y

What I claim as new and of'niy invention, and desire to secure by Letters Patent, is

. l. lnalubricating apparatus, the combinav tion oi' a piston, a valved dip-tube rigidly con- When 4 nected to said piston,and an oil-cup into which 5 said tube is adapted to dip, 'substantially as described.

4.. In a lubricating apparatus', the comhination of a cylinder open at one end, an oil-cupA vlocatedoin said open end, an oil-reservoir, pipes connecting said cup and reservoir, a

piston, and a di p-tuhe rigidly attached-to said 7 K. SMITH.'
